Abstract

In order to inhibit the deterioration of a photocatalyst-containing detergent and thus keep the bactericidal, deterging and deodorizing effects thereof, provided is a detergent characterized by containing a photocatalyst, a fine powder of an active carbonaceous material, and cyclodextrin. The active carbonaceous material is preferably charcoal or activated carbon. Since the detergent contains not only a photocatalyst but also a fine powder of an active carbonaceous material, the oxidation in storage, which is due to the photocatalyst, can be inhibited by the light-shielding property of the fine powder, so that the effects of the detergent can be inhibited from deteriorating. Further, the detergent exhibits an efficient coordinated effect of adsorbing excessive sebum, stains in the pores of the skin, metabolic decomposition products, odors and so on by virtue of the porous structure of the active carbonaceous material, and decomposing these adsorbates through the action of the photocatalyst.

Description

Washing soap

The present invention relates to a cleaning agent capable of preventing deterioration of a cleaning agent containing a photocatalyst and maintaining a sterilizing, cleaning, and deodorizing effect.

Conventionally, components contained in cleaning agents (for example, shampoos) used in the human body, among cleaning agents, have been more gentle to the skin and mucous membranes because they are in direct contact with the human body, and also have sterilizing power, cleaning power, deodorizing power, etc. What has a high effect is required.

Therefore, a cleaning agent to which a photocatalyst has been added has been proposed so far (see, for example, Patent Document 1).

Photocatalyst is a general term for substances that exhibit catalytic action when irradiated with light, and titanium dioxide is known as a representative one. The photocatalyst has an action of decomposing organic substances by an oxidation-reduction action when irradiated with light. Therefore, if it is added to the cleaning agent, it is possible to remove bacteria, sebum, malodor and the like. As a result, if it is a shampoo, for example, effects such as hair growth promotion can be obtained.

Japanese Patent Laying-Open No. 2005-082708

However, the conventional photocatalyst-containing cleaning agent has a problem that the oxidation reaction of the photocatalyst gradually proceeds in an environment where light is irradiated, and the components of the cleaning agent are decomposed by the photocatalyst. In stores, homes, etc., it is difficult to store the cleaning agent in a light-shielded environment, and as a result, the original sterilization, cleaning, and deodorizing effects of the photocatalyst deteriorate with time. In particular, such a problem is likely to occur in a liquid cleaning agent.

In view of the above-described conventional problems, an object of the present invention is to provide a cleaning agent capable of preventing deterioration of a cleaning agent containing a photocatalyst and maintaining a sterilizing, cleaning, and deodorizing effect. .

It is a figure explaining the function of the photocatalyst and apatite complex contained in the cleaning agent of the present invention.

Hereinafter, embodiments of the present invention will be described in detail.
The cleaning agent according to the present invention is characterized by adding a photocatalyst, fine powder of charcoal that is activated carbon, and cyclodextrin. As this charcoal, charcoal or activated carbon is particularly suitable.

Here, charcoal is charcoal obtained by heating and carbonizing a plant tissue such as wood in a semi-sealed state. Activated carbon is charcoal with strong adsorptive properties subjected to chemical or physical treatment (activation, activation).

Charcoal and activated carbon have the property of being porous. That is, it has a structure with innumerable pores, and it is possible to capture and adsorb fine substances in the pores. For example, black coal (charcoal obtained by carbonizing wood using an earthen kiln) has a large surface area of 200 to 300 m ² per gram. The larger the surface area, the stronger the adsorption power. For activated carbon, the surface area is 900-1300 m ² per gram. Therefore, activated carbon is particularly excellent in adsorption power.

When such charcoal or activated carbon is added to a cleaning agent containing a photocatalyst, excess sebum, pore dirt, keratin, waste, odor, etc. can be adsorbed into the pores. Furthermore, it is possible to efficiently exhibit a coordinated action that the photocatalyst decomposes these adsorbates.

The fine powder of charcoal is generally black (charcoal black). Therefore, by adding the fine powder of charcoal, the liquid color of the cleaning agent becomes black, and the light-shielding property prevents the oxidation reaction of the photocatalyst during storage, thereby preventing the deterioration of the effect of the cleaning agent.

Thus, in the cleaning agent of the present invention, by adding a fine powder of charcoal in addition to the photocatalyst, while exhibiting a high sterilization, cleaning, and deodorizing effect in cooperation with the photocatalyst, the deterioration of the cleaning agent is prevented. It is possible to maintain the above effects.

The photocatalyst used in the present invention is preferably composed mainly of titanium dioxide, or one or more of zinc oxide, vanadium oxide, dibismuth trioxide, tungsten trioxide, iron oxide, and strontium titanate. It is.

The photocatalyst used in the cleaning agent of the present invention is preferably a complex with apatite. Therefore, hereinafter, the photocatalyst and the apatite composite will be described.

FIG. 1 is a diagram for explaining the functions of the photocatalyst and apatite composite contained in the cleaning agent of the present invention.

Apatite refers to a group of minerals having a composition of M ₁₀ (ZO ₄ ) ₆ X ₂ where M, Z, and X are arbitrary elements. The main components of M and Z are calcium and phosphorus, respectively, but M, Z, and X can be replaced with various elements relatively easily. For example, when calcium is contained in M, phosphorus is contained in Z, and fluorine is contained in X, fluorinated apatite (fluoroapatite) is obtained. Further, when calcium enters M, phosphorus enters Z, and a hydroxyl group enters X, it becomes hydroxyapatite (hydroxyapatite). A function well known as an apatite function is a function of adsorbing and holding harmful chemical substances. For example, bacteria such as nitrogen oxides, lipid peroxides, ammonia, aldehydes, and Escherichia coli can be adsorbed.

The photocatalyst and the apatite complex are produced by combining the photocatalyst and apatite by a method such as coating (covering the photocatalyst with apatite), substitution (substituting the photocatalyst in the crystal structure of the apatite), or the like. Then, the actions of both the photocatalyst and apatite can be linked to efficiently adsorb and decompose harmful organic substances, bacteria, malodorous substances and the like. For example, photocatalysts generate very strong oxidizing power when irradiated with light, and can decompose harmful chemical substances and bacteria that have come into contact with them, and decompose them into carbon dioxide gas. There is no attracting action or a large amount of adsorbing action, and only substances that contact the photocatalyst surface can be decomposed. Also, it cannot function unless it is exposed to light. Apatite is also excellent in the ability to adsorb substances, and can be adsorbed in large quantities. However, since there is no resolution, the apatite will saturate if it exceeds a certain adsorbed amount and cannot adsorb any more.

However, when this photocatalyst and apatite are combined, as shown in FIG. 1 (a), a substance can be adsorbed while not exposed to light, and further, as shown in FIG. Since the photocatalyst decomposes the substance adsorbed, the adsorption function is restored each time. Furthermore, the photocatalyst requires a certain time when decomposing the organic substance, but since the substance adsorbed by the apatite is not missed, it can be decomposed reliably.

In the cleaning agent according to the present invention, by adding the photocatalyst and the apatite complex to the charcoal having the above-described effects, the apatite adsorbs harmful chemical substances, malodorous substances, bacteria, etc., and the photocatalyst decomposes them. It can be set as the cleaning agent which has the outstanding disinfection, washing | cleaning, and deodorizing effect by the cooperation effect | action of removing. When applied to shampoos, the scalp can be kept healthy and hair growth promoting effects can be obtained.

The apatite used in the present invention is preferably fluorinated apatite or hydroxide apatite.

In the cleaning agent of the present invention, silicon dioxide may be further added in order to reinforce and strengthen the above-described effects of the photocatalyst and apatite.

In the present invention, cyclodextrin is further added which enhances the action of the photocatalyst and exhibits a specific effect. This cyclodextrin is a cyclic oligosaccharide in which glucose is bonded to a cyclic structure, and the inside of the cyclic structure has pores that are large enough to include other molecules. This pore has a unique structure that is hydrophilic on the outside and hydrophobic (lipophilic) on the inside, and various molecules can be taken into the pore to form an inclusion complex. Therefore, conventionally, this inclusion function has been used to increase the stability of guest molecules (encapsulated molecules) and to remove malodors and foods. It has been confirmed by experiments that the action of such cyclodextrins is combined with the photocatalyst and apatite, and the above-mentioned effects of the photocatalyst and apatite are drastically improved. That is, when the amount of the photocatalyst and apatite is constant, cyclodextrin is not added on the one hand, and on the other hand, when cyclodextrin is added, the photocatalyst and apatite complex decompose and remove harmful chemical substances, malodorous substances, bacteria, etc. The rate is 3 to 6 times greater when cyclodextrin is added than when cyclodextrin is not added.

Of the cyclodextrins, those with 6 glucoses are called α-cyclodextrins, those with 7 glucoses are called β-cyclodextrins, and those with 8 glucoses are called γ-cyclodextrins. The cyclodextrin referred to in the present invention includes not only these α-cyclodextrin, β-cyclodextrin and γ-cyclodextrin, but also cyclodextrin derivatives and related compounds.

Here, the effects obtained by adding the above cyclodextrin to the cleaning agent of the present invention include the following. First, cyclodextrin can include malodorous substances and harmful chemical substances. Since this inclusion is performed immediately, the deodorizing and cleaning effects appear immediately. And the photocatalyst decomposes them. In this way, sebum, dirt, odor, bacteria, etc. are removed.

Incidentally, cyclodextrin is also an organic substance, but unless the photocatalytically active substance is irradiated with strong light above a certain level, cyclodextrin is not decomposed by its photolytic action. Therefore, even when cyclodextrin and a photocatalyst coexist, cyclodextrin is not decomposed in a liquid containing fine charcoal powder.

Thus, it is possible to improve the action of the photocatalyst by further adding cyclodextrin.

Furthermore, an activator that activates the photocatalytic effect may be added to the cleaning agent of the present invention. For example, preferably sodium sesquicarbonate or amino acids, acid salts of amino acids, alkali salts of amino acids, sodium percarbonate, sodium persulfate, aluminum hydroxide, aluminum hydroxide / magnesium carbonate / calcium carbonate coprecipitate, aluminum hydroxide Magnesium, aluminum hydroxide / magnesium hydroxide coprecipitate, aluminum hydroxide / sodium bicarbonate coprecipitate, aluminum glycinate, calcium acetate, calcium bicarbonate, calcium borate, calcium carbonate, calcium citrate, calcium gluconate, Calcium glycerophosphate, calcium hydroxide, calcium lactate, calcium phthalate, calcium phosphate, calcium succinate, calcium tartrate, dibasic sodium phosphate, dipotassium hydrogen phosphate, diphosphate Lithium, disodium hydrogen phosphate, disodium succinate, dry aluminum hydroxide gel, L-arginine, magnesium acetate, magnesium aluminate, magnesium borate, magnesium bicarbonate, magnesium carbonate, magnesium citrate, magnesium gluconate, water Magnesium oxide, magnesium lactate, magnesium metasilicate aluminate, magnesium oxide, magnesium phthalate, magnesium phosphate, magnesium silicate, magnesium succinate, magnesium tartrate, potassium acetate, potassium carbonate, potassium bicarbonate, potassium borate, citric acid Potassium, potassium metaphosphate, potassium phthalate, potassium phosphate, potassium polyphosphate, potassium pyrophosphate, potassium succinate, potassium tartrate, sodium acetate, heavy coal Sodium, sodium borate, sodium carbonate, sodium citrate, sodium gluconate, sodium hydrogen phosphate, sodium hydroxide, sodium lactate, sodium phthalate, sodium phosphate, sodium polyphosphate, sodium pyrophosphate, sodium succinate, tartaric acid Sodium, sodium tripolyphosphate, synthetic hydrotalcite, tetrapotassium pyrophosphate, tetrasodium pyrophosphate, tripotassium phosphate, trisodium phosphate, trometamol, perborate, carbonate, metasilicate, citric acid, bicarbonate An active agent selected from the group consisting of sodium, calcium silicate, or a mixture thereof is added.

In addition, to the cleaning agent of the present invention, a plant essential oil obtained from one or more of natural plants including lavender, rosemary, sweet orange, cedarwood, chamomile, peppermint can be added to obtain an aroma and a specific effect. You may do it. If these are included in the cyclodextrin in advance, a fragrance can be obtained at the time of use. In addition, beeswax, honey, coconut milk powder, seaweed, brown sugar, yogurt, egg yolk and the like may be added as a moisturizing agent.

Here, the cleaning agent referred to in the present invention refers to a cleaning agent used for the human body, and is particularly preferably a shampoo. Alternatively, it is any of body shampoo, hand soap, makeup cleansing agent, facial cleanser, and kitchen cleaner.

Here, it is preferable that the container for storing the cleaning agent is formed of a light shielding member that prevents light from entering from the outside.

As described above, according to the cleaning agent of the present invention, by adding a fine powder of charcoal in addition to the photocatalyst, the light-shielding property prevents the photocatalyst oxidation reaction during storage and prevents the effect of the cleaning agent from deteriorating. can do.
